I usually start my period on the 15th of every month, and it's been that way for the last 5 years or so. In July, I didn't start on the 15th, which was a Sunday. Beginning on Monday, the 16th, and everyday that week up to Saturday, I had unprotected sex with my fiance and he came inside of me everytime. I started my period on the 22nd; and it was pretty normal as far as I can remember. Now, it's September 8th and I have not had a period since July, but also have not had sex since before my last period. I've been reading a lot on this subject and the answers keep jumping around. I will be happy if I am, just want to know if it's even remotely possible. Anyone have any answers and/or suggestions? Thanks! :-D
